I '0 all whom it may concern:

Be it known that we, KIHAGHIRO KoBoRI and RYoIoHI NArro, subjects of the Empire of Japan, resident, respectively, in care of business department of Kanegafuchi Boseki Kabushiki Kwaisha, Higashi-Shiri-Ike, Kobe, Japan, have invented certain new and useful Improvements in Cocoon-Dropping Apparatus for Use in Silk-Reeling Machines, of which the following is a specification.

Ourinvention relates to improvements in cocoon dropping apparatus for use in silk reeling machines. Theobject of the invention is to provide an apparatus for dropping cocoons, with their filaments unloosed, one by one and supplying them to the silk reeling machine mechanically by merely depressing a plunger.

The apparatus of the invention is to be applied to silk reeling machines of the type provided with a special filament supplier.

The accompanying drawing shows an ex ample of the apparatus of the 'present invention. Fig. 1 is a side elevation of the apparatus as applied to a silk reeling ma chine, only a part of the reeling basin and the filament supplier shown. Fig. 2 is a side elevation of the cocoon disk and the con duit tube partly in section as seen from the left side of Fig. 1. Fig. 3 is another side elevation of same as seen from the right side of Fig. 1.

In the drawing, (1) represents a part of the frame work of the silk reeling machine; (2) a reeling basin; (3) a filament supplier comprising a set of toothed wheels arranged adjacent each other and revolving in the same direction; (4) filament collector with a fine hole at its centre.

According to the present invention a cocoon disk (5) provided with several cylindrical recesses (6) radially disposed at equal distances on its periphery, for receiving each a cocoon therein, is vertically mounted onthe frame work above the reeling basin (2) by its horizontal axis (7) and is adapted to be turned by a ratchet mechanism hereinafter described. Beneath the cocoon disk a guide tube (8) is vertically arranged. The upper open end of said tube terminates below the cocoon disk and the recesses in the latter are adapted, during rotation of the disc, to be successively brought into registration with the tube, the end of the latter term nating above the basin'at the side of filament supplier A guide plate (9),

concentrically curved along one sideof the lower part of the cocoon disk, is fixed at the top of the guide tube for supporting cocoons carried along during rotation of the cocoondisk and permitting them to drop in turn into the guide tube.

The ratchet mechanism comprises a ratchet wheel (10), the teeth of which correspond to the number of the cocoon recesses (6). Said ratchet wheel is fixed on the axis (7) and coacts with a'restraining EL pawl (11) pressed by a spring (12). sliding bar (13) is vertically arranged and provided with a slot (14) receiving the axis (7) and pulled downwards by a spring (15). At one side of the sliding bar a driving pawl (16) is pivoted and is pressed against the ratchet wheel (10) by a spring (17). The lower end of the sliding bar is connected to a lever (18) fulcrumed on the frame, and the other end of said lever is connected through a link (19) to a lever (20) fulcrumed underneath the reeling basin and connected at its opposite end to a plunger (21) vertically arranged at the side of the reeling basin.

The operation of the apparatus is as follows The filaments of cocoons in the reeling basin (2) are collected together passed through the supplier (3) and the collector (4) to form a silk strand, and after passing the part of Kennel apparatus is wound on the reel as in the known silk reeling machines. Each recess (6) of the cocoon disk (5) is previously filled with one boiled cocoon and the ends of the filaments of these cocoons are collected together and tied on a stem (22) formed at the front end of the axis Now in the course of reeling silk when it is desired to supply a filament, the operator depresses the plunger (21) by hand. The sliding bar (13) is elevated through the action of the lever (20), link (19) and the lever (18), and a pawl (16) drives the ratchet wheel (10) so-that the cocoon disk (5) is turned. The restraining pawl (11) then engages the next tooth of ratchet wheel (10), thus the mechanism advances by one tooth of the ratchet wheel. When the plunger (21) is released the mechanism returned to initial position the spring 15 A s the teeth of the ratchet Wheel correspond to the number andposition of the cocoon recesses, the next cocoon recess 'is brought by turn in alignment with the upper end of the tube ('8) by the revolution oithe disk (5). The cocoon, received in said recess and previously su' portecton'the guide plate (9), drops then into the tube (8) with the end ofits filament held on the stem (22) and thefilanient pulling off ofthe cocoon as the latter ,COntlnues to fall. Thus cocoons received the cocoon recesses are mechanioally dropped one by one as often as the plunger '(21) is pushed.

The filament of the falling cocoon is caught by one of the toothed Wheels of the filament supplier (3) While falling beside it, and by the revolution of said toothed wheel the filament is caught by the adjacent toothed vvheel so that his united with other lilainentsinthe course of reeling. We claim l. A cocoon dropping apparatus comprisn a r t b e di m nded w th p p eral'oo'cbmreoeiying recesses, a CQGQQIl guide tube arranged below the disk, said recesses adapted to be successively brought into registrationvvith the upper end 'ofsaid tube, a filament sup lier "arranged below the tube, e uide op ate extend n a era y of the uppetendof "the tube and in close'eoncentric relation to the contiguous portion of the ai'signndmafis for rotatably advancing the disk step by step.
